hey i dont have any yoyos that use hubstacks but i was wondering what do hub stacks do and what are some features of them and i was also wondering if i could put some hubstacks on a peter fish luminator yoyo and if i could, is there a easy way to do it without any magor tools

Hubstacks just let you hold onto the yoyo while it’s spinning by the sides. There are some people doing tricks using them but there’s not a huge amount of hubstack tricks being worked on right now. As far as the Peter Fish, I’m not sure since I haven’t seen one before.
